the shaft 145 b he window adjuster, to o n To operate t .the window (see Figs 1, 2, 2", 6) `the en of thephandle 50 is inserted into 'the sleeve 46 to lock the slot 51 with the locking pin 44. The handle 50 is turned as indicated by the arrow A, which by means of the pinion 45 and the spur ear 41 moves the rack 36and with 1t the sllde bar 35 in the direction ofl the arrow B. Thereby the pins 57, 59 and the key 55 'are also moved in the direction of said arrow B. The key 55 strikes the heel 137 of the latch arm 135 and thereby moves the link 140 in the direction of the arrow C, until the arm 135 strikes the stop pin 61, by means of which the latch shaft 145 is turned in the direction of the arrow D, and the latch 157 is released from the latch pin 156. At the same time the pin 57 moves in the direction of the arrow B to enable the arm 135 to swing. The link 72 is moved by the pin 59, which swings the short arm 64 in the direction of the arrow E and the long arm 65 in the direction of the arrow F, by virtue of which the window sash swings in the direction of the arrow G, (to its open position as indicated in Fig. 4) on the pin '127 of the member 117 of the hinge already described, the

.roller 100 rolling in the gulde opening 105 of the arm 104. With the movement of thc link 72 in the direction of the arrow B the pin 59 moves in the elongated opening 73 of said link 72, and the latch 78 is locked With said pin 59.

The operator may maintain the windo'..

l sash in different angular open positions, by

swinging the operating handle 95 in the direction of the arrow H, which locks the locking pin '86 with one of the locking openings 69 inthe journal pin- 66.

To close the window sash, see Figs. 1, 2, 3, 4 and 6, the operating handle 50 is turned in a direction opposite to the arrow A, and thereby the slide bar 35 is moved in a direction opposite to the arrow B. By this means the pin 59 moves from the position indicated in Fig. 4 to the position shown in Fig. 3, and during its movement the latch 78 contacts with the adjusting screw 97 and said latch unlocks from the pin 59, which rmlits the 'pin to further move in the e ongated opening 73 of the link 72. The pin 57 moves with the pin 59. The latter strikes the heel 137 of the latch arm 135, whereby the link 140 moves in the directionof the arrow I, (Fig. 3), and the latch 157 locks with the latch 1n 156 and the window is securely locked 1n its closed position as indicated in Fig. 1. The arm 104 during the operations described is locked to the sash by means of the latch 111, and after the window is partially olpened, if it is desired to space the sash from t e jamb 20, to which it 1s hin ed as indicated in Fig. 5, the latch 111 is irst released from the arm 104, and the latch 121 is released from the hinge member 116 to which it was locked. The operator may now manually space the sash to the position shown in Fig. 5, to be enabled to clean the outer face of the window.

Various modifications may be made in the invention and the present exemplification is to be taken as illustrative and not limitative thereof.
